l Letters raam; No. 112,372, daad March 7, 1871- `IMPROVMEINT IN BORING MACHINES.

The Schedule referred to inthese Letters Patent and making part of the Bame.

ljf, Joan HnNRvPARnIEoLof Acton, in the county of Marion and'Statefof Indiana, have invented certain Improvements ih Boring Maohines,of which the following isa specification.

` Nature aadeObjects of the Invention. t The lirst part of my invention relates to boring fel- I lies and other,4 parts of the wood-Work of wagons, and

it consists inthe arrangement of an, adjustable table, won which to place the articles to `be bored, combined l with an adj ustablehorizoutal boring machine, having forits object'to bore fellies and-other parts of the ivood-workof wagons with greater facilityand 'precis- :lon than heretofore. V

The second part of` the invention relates to boringl hubs` and-tenoningispokes, and it consists in the arrangement ofan adjustable holder for the hub, and also for the spoke, combined With1the boring appa- I, J'atns, having forits object to bore'hubs and tenon spokes with more precision and greater-rapidity than has heretofore been achieved by hand-machines.

The arrangementof theseveral parts is such as to l "combiney in one ,simple andetlcient machine the re-` ing my invention. I

Figure 2 isa side elevation of the same.

Figure 3 isfa transverse vertical section on the line xz.,iig.l.

l A is the frame of the machine, to-'which all the other parts are attached.

B isa horizontal sliding frame of metal or other suitable material, in which is hung the gearing G .D and crank E, for giving rotary motion to the angel'- shait E, all constructed and arranged in the usual manner. i

The frame Bis `moved by`means of the lever G, which, is pivoted by its lower endfat-H, and passes up through an eye, I, on the side of the frame, as shown.

J is a table, adj usted both vertically and -longiti1d `nally, upon which to lay fellies, or other articles tov `be bored. 'When used for fellies', the movable rest K, formed to fit the inside thereof, is placed on the table as shown in ligs. l-'and 2.Y

L indicates a telly in position by the screw a. The table is adjusted longitudinally by means of a rack on the under side (not shown in the drawing) and a pinion operated bythe hand-Wheel M,and vertically by means of theslotted legs N, through which set-screws,

0, pass into the legs A. of the frame.

For convenience of boring hubs, and also for tenoning spokes, I it an upright rod, Q, on which to place the hubas shown in tig.- l, said rod beingaL screw furnished 'with nuts c e, in order to adj ust the huh vertically in a horizontal adjustable sliding-bar B.,'Whchv is secured to the under side of the table byagpet screw,

W, and by which the hub may be arranged at the proper distancefrom the auger for tenoninispokes'of large or small Wheels.

`ln order to hold the spokes lirmly while cutting the tenons on the end, I have devised the clamp com posed ot' the vertically-adjustable plate S, to the -upper end of' which are hinged the arms T, between which the spokes are held, as shown in rigs. l and 3. A,link,V, serves to hold the arms 'l firmly to the spoke.

Claims.

I claim as my -inventionf- 1. The boring and spoke-tenoning machine,.com posed of the vertically and horizontally-adjustable Ytable J, `provided with the movable rest K, boring apparatus B C D l.) F G, huhholder Q e e'R, and spoke-holder S ,'ll V, all constructed and arranged substantially as and for the purpose set forth.

2. The vertical rod Q, provided with nuts e e, and h'xed in the adj usltable bar R, iu'combinationwith the boring apparatus specilied in the first clause of claim, and the spoke-holding device, composed of the vert-ically-adjustable plate S, arms T, and link V, arranged substantially as and for the purpose set forth.
